To refresh air in a room, a counter flow heat exchanger is mounted in the wall. It draws in outside air at 33 F, 80% relative humidity and draws room air, 104 F, 50% relative humidity, out. Assume an exchange of 6 lbm/min dry air in a SSSF device, and also that the room air exits the heat exchanger to the atmosphere at72 F. Find the net amount of water removed from room, any liquid flow in the heat exchanger and (T, ) for the fresh air entering the room.
